Hello Guest!
Welcome to the official Square Foot Gardening Forum.
There's lots to learn here by reading as a guest. However, if you become a member (it's free, ad free and spam-free) you'll have access to our large vermiculite databases, our seed exchange spreadsheets, Mel's Mix calculator, and many more members' pictures in the Gallery. Enjoy.

Ok, the weeds obviously had a party in my garden this fall/winter/early spring. I am kinda at a loss what to do. Yes, I need to pull them - but I was starting to have trouble with some of them last year so they are very resilient and some are very hard to pull (or even dig out - see picture #3). I am going to be relocating my boxes so I need to de-weed, dig out the dirt and go from there. My question is, I found on Pinterest a week-kill formula using vinegar, salt, and dawn. If I use it, will it render my soil un-usable for growing veggies this year? I'm going to attempt to include some pictures so you can see what I'm dealing with. Thanks for any advice you can offer!

You said you needed to move your boxes so since you need to empty themthis is what I would do.

If you are using Mel's Mix I would scoop out the soil and using your fingerssift out all of the weeds and root pieces you can then re use the soil. I hadto do this with one of my boxes this spring (I will be putting a plastic coverover my boxes this fall.)

If you have used soil from your yard I would get some Black plastic and siftout as much weed and root as you can then tightly seal the soil in the plasticand let it bake in the sun for a couple of months that should kill whats left without chemicals.

I remember watching control-burned sugar cane fields in Hawaii... It would be nice to think a blow torch would quickly get rid of your weeds, then turn up and expose the roots and torch it again. But I bet peat burns and the wooden sides are an issue too
